I received an email from CPS saying about the recall notice on some of the 1DX's, unfortunately mine was one that fell in that group...
Before it was set away it was perfect nothing wrong with it, focus locked on every time etc... Now after receiving it back from canon it sometimes struggles to lock on even to simple things, yesterday I was using it a falconry show and manage to get the Error 80 come up. The focus screen, mirror and sensor have been flicked with looks like oil. Not really sure how I can move forward with this now.
Any advice would be much appreciated
